ABit AX78 Overclocking/Stability

**LIKMARK** · 03-14-2008, 03:57 AM

AOD read my idling temps as 24 degrees celcius (water), bios read them as 41 degrees, speedfan read them as 41 degrees idle, 56 degrees load. Not sure wich ones to believe, most possibly none of them reads temps right.

Abit EQ =-> good laugh.

Edit: NB volt 1.1 is the memcontroller voltage control yes?
NB volt 1.8 is the nb voltage control

do you have any OC results with motherboard capabilities? like, does it exceed in areas where other boards dont....
I ask cuz Im extremely interested in this board =) and want to know its OC abilities.
With the Phenom that is =)

**LIKMARK** · 03-15-2008, 10:53 PM

Well, thing take time..

I'm doing 2,5GHz at 1,30 vcore (can probably go lower on the vcore) stable.
No exeptional overclock.. This is without changing NB fid as this bios don't allow for that, will have to try it out with BAR EDIT.

KTE:Winrar reported the bios zip as: Unexpected end of archive. Could you upload it again?

**KTE** · 03-16-2008, 01:40 PM

It's an issue with your download being incomplete and in broken bits due to network line jumps. I've been having it a lot lately too but attempting to download 2-3 times fixes the problem. I've just downloaded it now to try and the links is fine, try again after clearing your browser cache.

**LIKMARK** · 03-18-2008, 12:33 AM

Had to download it seven times to get it

I tested downloading it four times before I wrote my last post.. Gonna test some nb multi changes tonight.

Beta Bios 13.b02
I had a lot of hangs from the bios after using f10 to save. This board and cpu combo has been a real chore so far and I've gone back to bios 12 for now.

Under cpu features, what is the stepping option about, where you've got P0 and P1 as options? Is that for enabling the TLB fix?

**LIKMARK** · 03-18-2008, 11:16 PM

Only booted once using the p1 setting, didn't test if it were disabling TLB patch as I'm running Sam2009's program for disabling it. Thanks for the warning about the beta bios, have note tested it yet.

Edit: BTW are your PC8500 ballistix keeping up with the Phenom? My PC6400 Ballistix (easily overclockable to above 1100MHz with Athlons) can't even run stable at CL4 @stock speeds.

**maxwedge** · 03-19-2008, 04:34 AM

I'm having a generally hard time with this board and at this point I've determined I having the same issues with bios 12, so I've gone back to the beta again. Mostly trying to pick voltages for the ram other than auto tends to make it hang. I can't get my ram to run well either and had them up to ddr1200 on my IP35 pro. I got the sticks to run at 800 4 4 4 12 volts at auto (2.0v) but had to drop the multi to 10x to do it. With the cpu at default it crashes at 4 4 4 12.
5 5 5 18 is ok with auto volts and cpu at default.

**Hazzan** · 03-19-2008, 05:23 AM

everybody if need new beta bios for this board !! I send to your email...PM me !!

No where even close to like X2/C2 oc and stability but I have and can run 1066 4-5-5-15 2.3VDIMM and 1000 4-4-4-4-11 1T 2.2VDIMM with Phenoms + Ballistix. Have to go easy on the NB in these scenarios though.

Some pics if anyone are interested:

Cinebench R10, 9500@2500Mhz, XP 32bit, AX78

Max stable overclock ATM: 2505Mhz

**KTE** · 03-22-2008, 07:15 AM

Looking good. Temps seem to be high, maybe they limited you or the NB?
Also 4GB is going to limit you, you might as well try with two sticks to try and see max CPU oc.
Can you post any BIOS oc option pics yet? (or I have missed them?)

BTW, just checked and a little correction. I've ran 1200 4-5-5-15 2.25 vDDR with Phenom.

**LIKMARK** · 03-22-2008, 07:41 AM

Haven't tested much yet, but four sticks seems to limit ram overclock, as expected, but not cpu overclock. Temps are high, a lot higher than I would believe under water, maybe sensors are showing too high temps. I'm thinking it's a combination of nb and general bad overclocking performance limiting me. You remember where you posted the nb fid register values in your MSI thread?
And just to be sure, nb speed could not be lower than ht link speed? Right, or was it the opposite...

Should be able to take som pics of bios..

Edit: Sorry for using slooooow loading imageshack...
Edit 2: Damn, thats one dusty LCD monitor :p

**freeloader** · 03-24-2008, 05:56 AM

Does anyone have a problem with Coretemp on this board with a 5000+ Black Edition processor? It shows my core temps as below 10 degrees C. Not likely as I'm on air....LOL

**LIKMARK** · 03-24-2008, 06:16 AM

Thats a problem known with the Brisbanes rather than the board I think.

I can't change nb multiplier with Phenom on this board (with BAR EDIT). Anyone got any ideas?

**freeloader** · 03-24-2008, 06:55 AM

Thanks for the heads up!

I've been playing with this combo for a few hours now. I've noticed that my on board NIC dies about every hour and I need to restart to get it working again. Does anyone else have this problem?

**cygnus_x_1** · 03-24-2008, 02:18 PM

anyone in the US with this board that is willing to hot flash my bios? i killed mine trying to flash in vista, i know im a putz, but abit's tech support is taking forever getting back to me if they have replacement bios' available.

**Cheffy** · 03-26-2008, 01:15 AM

Anyone here got any issues with the PWM temps sky rocketing?

6400+BE, 1.4v (stock) orthos = ~70c pwm. 1.45v = 80c pwm, i was trying 3.5ghz/1.5v but pc shutoff and pwm temp was reading like this as it updated from idle to shutdown: 30, 45, 60, 73, 84 (shutdown) - the heatsink was pretty much cold to the touch but visual inspection seems to show its contacting correctly..

otherwise everything seems to be working nicely.

**LIKMARK** · 03-26-2008, 01:57 AM

Pwm temps with priming Phenom @2500MHz @1,35v = 51 degrees celcius with a 80mm 1800rpm fan blowing at the heatsink. Heatsink feels cold to the touch. You tested reseating the heatsink?

**Cheffy** · 03-26-2008, 05:32 AM

ill try when i get home.

i wish i had a removable tray

lol

- im now all AsC'd up.. basically no change to temps :/ ill just avoid high v-core i guess

thanks anyway

**LIKMARK** · 03-29-2008, 12:32 AM

Any luck Cheffy?

I've got 2*2048MB of Dominators on my way in the start of april. Hoping they will play better with my Phenom at1066 speeds. Anyone tested this combination?

**Cheffy** · 03-29-2008, 06:34 AM

i pulled the sink off, everything looked to be contacting ok, replaced the rubbery pad (easy to peal off!) with arcticsilver ceramic.. temps down maybe 5-10c. but not a great deal. still hitting 70c at 1.45v/3433mhz..
i think i just have a poorly calibrated diode.

motherboard seems to have little to no issue with high fsb for x2's, running 286 atm without touching voltages, ht link at 1143. when i get round to it ill test max-posting fsb with 5x multi.

***EDIT***

i got 300 fsb no problem but 333 always hung/auto reboot and gave the error "The CPU Frequency has been over running" - this was with all stock voltages and 3x ht multi and 5x cpu. so id say 11x is the lowest multi for use for trying to hit 3300mhz+ on an x2 for my board. your milage may vary, and i didnt explore settings for long

***END***

as a side note, the ax78 is applying the selected multplier at powerup unlike the AX8 (939/via 890) which started on default multi then dropped it. so im not used to running fsb much over 250
